B Grade Sandstone
Retaining Walls

B-Grade sandstone provides a balance of strength, durability, and natural character at a more economical price point than A-Grade. Each block has slightly looser tolerances and more rustic edges, while still delivering a highly functional retaining wall.

Stage 01

Initial Consultation

 We discuss your project requirements, style preferences, and site-specific considerations to create a shared understanding of the project goals.

Initial Consultation

Stage 02

Site Assessment & Planning

 Site conditions, soil type, and drainage are assessed. A design plan is developed, balancing structural integrity with the natural, slightly varied look of B-Grade sandstone.

Stage 03

Construction

B-Grade blocks are carefully placed to achieve a functional and aesthetically pleasing wall, with on-site adjustments to accommodate natural variation.

Stage 04

Handover & Support

Once the project is complete, we walk you through the site to ensure everything meets Australian standards and most importantly your expectations, and furthermore confirm that the project is ready for sign-off.

B-Grade sandstone blocks are partially sawn and partially split, generally four workable faces. Dimensional tolerances are wider than A-Grade, requiring greater on-site adjustment and placement during construction.

Block sizes are usually 1000 mm in length, 500 mm in height, and 500 mm in depth, though irregularities are more common due to quarrying methods. The compressive strength remains suitable for engineered retaining wall applications, but installation may involve increased time for fitting and levelling.

Recommended for projects for all types of retaining, including seating, boundary walls, garden features, or informal landscapes. It is valued for its affordability, strength, and more natural aesthetic.
